a storeowner made a list of the number of greeting cards sold last month. The store sold 167 thank you cards, 285 birthday cards, and 56 blank cards. Based on this data, which number is closest to the probability that the next costumer will buy a blank card?
Well to solve this we can take 167+285+56=508 then we can take 56/508=.11 to find the probability that the next user will buy a blank card, meaning that there is a 11% probability that the next customer will buy a blank card.

Answer: There is 11% chance that the next costumer will buy a blank card.
Step-by-step explanation:
Since we have given that
Number of thank you cards = 167
Number of birthday cards = 285
Number of blank cards = 56
So, Total number of cards is given by
167+285+56=508
So, Probability that the next costumer will buy a blank card is given by
\(\frac{56}{508}\\\\=0.110\times 100\\\\=11\%\)
Hence, there is 11% chance that the next costumer will buy a blank card.
